Precision of method 13 Linear in range 0.1–10 µg/mL. RSD at 5 µg/g 1.7 % (n=5). Comparison study showed method was superior to GC method for established and applied to samples containing large amounts of reducing substances. Good real samples (n=5) agreement achieved between both methods for other foods. (n=3) 2.73±0.11
